How to configure Ruby intepreter for Eclipse

I started my ruby project in eclipse Indigo in Ubuntu 12.04 and have the same problem. If you installed ruby already and can create a ruby project in eclipse, then you can find/add interpreters by the following way:

1. Go to Window -> Preferences > Ruby > Interpreters
2. Click on Search button on the right, then eclipse will help you to find the ruby interpreters
3. Click OK button at the bottom

For my case, the location of the interpreter is /usr/bin/ruby

Without RVM :

Please type command whereis ruby in console.you will get the path like /usr/bin/ruby or /usr/local/bin/ruby to check which is correct interpreter path /usr/bin/ruby -v if you get version. that is your interpreter.

With RVM :

Please type command: rvm info

binaries:    ruby: "/home/<USERNAME>/.rvm/rubies/ruby-2.0.0-p247/bin/ruby"

copy this path and paste wherever you need enter you interpreter path.

It worked for me. and I hope it will help others as well.

Cheers!
